I have my first overnight duo booking later this week.
Anyone with advice or experience?
Not much of a challenge then !
Try & get as much sleep for the few nights prior so you are rested
Just as important as a bluey IMO
As tiredness will set in
I'd have a kamagra gel sachet to hand for a top up
They work pretty instantly
Or have the other half of the tablet you reference
& i'd have a spare tablet pre cut in half
Unless you have some particular health issue where more than one tablet [spread out over a period of time] might not be a good idea
You mention not drinking, tho i would suggest arranging some beverages for the SPs
Makes for a more convivial atmosphere
They can decline, their choice
